I have a helix 10 2d that has went bonkers, need some guidance. Yesterday morning it was working fine, then in the afternoon it got too where it wasn't picking up the bottom and the temp was reading real low, if I turned the motor to the left, it seemed to be ok. Using it on an ultrex with the universal sonar, at the end it don't matter which way the motor was pointed it still would not read right, any suggestions? Thanks
